The nuclear powered submarine HMS Tireless has returned to Devonport at the end of her last deployment. The 30 year old boat has been helping in the search for the missing Malaysian airliner off Australia.

Most of her life has been spent as a hunter-killer submarine on top secret missions beneath the Atlantic Ocean, but three years ago she completed the longest deployment ever by a Royal Navy submarine on a ten month world tour.

A twenty three million pound rehabilitation centre for injured servicemen and women will officially open today at Devonport. It's been paid for by the charity Help for Heroes and the Ministry of Defence.

The centre is home to a gym and swimming pool, with doctors and personal trainers on hand to help injured soldiers recover.

The Royal Navy has confirmed that a training torpedo was accidentally launched inside Devonport Naval base in Plymouth on Wednesday. No one was hurt in the incident in which a test torpedo was "jettisoned onto the wharf."

Royal Navy statement:

We can confirm an incident occurred onboard HMS Argyll on Wednesday 12th March at 3.24pm, while the ship was alongside at Devonport Naval Base in Plymouth.

During a training exercise, an inert Test Variant Torpedo (TVT) unexpectedly jettisoned onto the wharf. There was no explosion and no casualties.

An investigation is now under way to determine the cause of the incident.

HMS Argyll was conducting a system test when an inert Test Variant Torpedo was jettisoned unexpectedly. The torpedo is not an explosive hazard.

The specific details of the incident are subject to further investigation and it would be inappropriate to comment further.

A Test Variant Torpedo is a dummy weapon with no explosive content.

There were no casualties involved.

No one was on the jetty at the time of the firing

The torpedo caused minor damage to an adjacent security fence (inside the naval base) where it landed.

The result of the investigation will determine what actions will be necessary to avoid any repeat of this incident in the future. However, torpedo system test firing alongside in the naval base has been suspended subject to completion of the investigation.

Hundreds of family and friends lined the quayside at Devonport for the return of crew members on board HMS Montrose. The ship had been away for seven months and helped with the removal of chemical weapons from war-torn Syria.
